Battery

Switching the battery on your key fob is one the easiest solutions. The fob uses a small coin-shaped 3V battery (CR2032 or CR2025) that is generally available in general stores or home improvement stores and some auto parts stores. Make sure you get a brand new battery -old batteries are usually not useful anymore and can damage the circuit board.

Start by removing the fob. It may be tight, but with the aid of a flat screwdriver you will be able split the two halves. After that, slide the screwdriver into the seams on both sides of the fob to lift up a couple of clips that hold it in place. They are easily broken so be cautious and work slowly.

Reassemble the fob after replacing the battery, and test to determine if it works as it should. If it doesn't work after pressing the button a few times, check that the contacts are clean. You can also test it with a spare key fob to determine if the issue is confined to your key. If it isn't, there may be another reason for why your key fob isn't functioning. It could be due to a worn-out button, for instance. This will only cause the button to work a few times and not always.

Interference

The key fob uses an insignificant transmitter to send a short-range radio signal to a receiver inside your vehicle. Its primary function is to allow your car to recognize the fob and unlock its doors when you approach and start when you press the ignition button inside.

The problem is, interference can interfere with this communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking your vehicle.

Other electronic devices operating on the same frequency could also interfere with the fob's signal. Garage door openers and tire-pressure monitoring devices can also be affected. It's even possible that an RF transmitter in your home might interfere with the fob's signals, though this would be difficult to pinpoint without an expert test.

It's also possible that the key fob is simply reset. The transmitter on the key fob needs to be recognized by the Mini's receiver. A unique code is used for each pairing. The fobs will typically need to be reset when they are removed or replaced, if you purchase a new one, and in some cases it's when a battery has been changed. To reprogram a fob follow the instructions in the owner's manual or contact a dealer for assistance.

Faulty chip

Modern electronic key fobs provide convenience and performance over traditional manual keys, however they can also be more susceptible to being damaged. A damaged chip is among the most common issues that can cause your key fob from operating properly. This is usually a simple fix.

If your fob is always failing to turn on your car, it is an indication that the chip is damaged. The problem can usually be repaired by replacing the battery that is inexpensive and simple to locate at a hardware store or big-box retailer. Make sure you purchase the correct battery compatible with the model of your vehicle to avoid any further problems.

It is also crucial to make sure that the fob isn't exposed to soapy residue. Water can cause corrosion and affect the circuitry. If this is the case, you'll require cleaning it with isopropyl alcohol or an electronic cleaner before putting in an entirely new battery.

It is a good idea to test the functioning of the fob before driving the vehicle. Test the voltage of the new battery with the help of a voltmeter to confirm that it's safe. If not then it may be necessary to replace the entire chip in the remote. A qualified dealer technician can help determine the best solution for you vehicle.
